Concept introduction:
Aldehydes and ketones with α-hydrogen undergo a base catalyzed carbonyl condensation reaction in aldol condensation. In this reaction two molecules of the reactant combine by forming a bond between α-carbon of one molecule and the carbonyl carbon within the same molecule or of the second molecule to give an aldol. The aldol dehydrates on heating to yield α, β-unsaturated aldehyde or ketone.
To show:
The structure of the aldehydes or ketones that should be used as a starting material to synthesize the compound given in an aldol reaction.

Concept introduction:
Mixed aldol condensation leads to a single product if i)one of the carbonyl partners contains no α hydrogen atoms but contains an unhindered carbonyl group and ii) if one of the carbonyl partners are much more acidic than the other and thus forms an enolate anion in preference to other.
To show:
The structure of the aldehydes or ketones that should be used as a starting material to synthesize the compound given in an aldol reaction.
